Effectiveness of the online mindset intervention 'The Growth Factory' for adolescents with intellectual disabilities.

BACKGROUND: This study examines participant satisfaction and effectiveness of the online mindset intervention 'The Growth Factory' (TGF) for youth with intellectual disabilities using a randomised controlled trial design. METHOD: Youth with mild to borderline intellectual disabilities (N = 119; 12-23 years) were randomly assigned to TGF (n = 60) or control group (n = 59). Primary outcome measures were mindsets and perseverance. Secondary outcomes were empowerment, mental health problems, self-esteem, treatment motivation, therapeutic alliance and challenge seeking. Measurements were conducted at pre-test, post-test and at 3 and 6 months follow-up. RESULTS: TGF had positive effects on perseverance, mental health problems, self-esteem and therapeutic alliance at post-test. TGF had follow-up effects on mental health problems (3 months), mindset of intelligence (3 and 6 months) and mindset of emotion and behaviour (6 months). CONCLUSIONS: TGF offers a promising add-on intervention complementing usual care programmes accelerating improvements in mindsets and mental health in youth with intellectual disabilities.

Mindset and perseverance of adolescents with intellectual disabilities: Associations with empowerment, mental health problems, and self-esteem.

BACKGROUND: Mindset refers to the implicit assumptions about the malleability of attributes such as intelligence, behavior, and personality. Previous research has shown that people endorsing a growth mindset show better academic and mental health outcomes than those with a fixed mindset. However, little is known about the mindset of youth with intellectual disabilities (ID) and its association with mental health. METHODS: Adolescents with (n = 247) and without (n = 96) mild to borderline ID completed questionnaires about mindset and perseverance, empowerment, mental health problems, and self-esteem. RESULTS: Adolescents with ID endorse a more fixed mindset of emotion and behavior than adolescents without ID. No significant differences were found for mindset of intelligence and perseverance. In addition, within the group of youth with ID some differences in mindset and perseverance were found based on level of intellectual disability, gender, and comorbidities, but not for age. Finally, a growth mindset of emotion and behavior and perseverance, but not mindset of intelligence, were negatively related to mental health problems in youth with ID. CONCLUSION AND IMPLICATIONS: Overall, findings indicate that teaching youth with ID a growth mindset of emotion and behavior and perseverance may be a potentially successful endeavour to improve mental health in adolescents with ID.

Study protocol: a randomized controlled trial testing the effectiveness of an online mindset intervention in adolescents with intellectual disabilities.

BACKGROUND: Adolescents with intellectual disabilities have an increased risk of developing academic, social, and psychological problems compared with non-disabled peers. These difficulties might have an impact on the implicit theories-or so called mindset-of these youth. Youth with a fixed mindset believe that their attributes are static while youth with a growth mindset believe their attributes are malleable. A growth mindset can positively affect the academic and psychosocial development of youth and can be stimulated by so called 'mindset interventions'. Nevertheless, mindset interventions specifically adapted to adolescents with intellectual disabilities are non-existing. METHODS/DESIGN: The aim of the present study is to conduct a randomized controlled trial (RCT) to test the effectiveness of the online mindset intervention "The Growth Factory" aimed to teach adolescents with intellectual disabilities a growth mindset and thereby positively impacting their psychosocial development. The RCT targets adolescents (12-23 years) with mild to borderline intellectual disabilities (IQ 50-85) admitted to residential care or special education. Participants will be individually randomized to the intervention (n = 60) or control (n = 60) group. The intervention group will individually participate in the six sessions of "The Growth Factory" and the control group will receive care as usual. Primary outcome will be mindset. Empowerment, behavior problems, self-esteem, treatment motivation, therapeutic alliance, challenge seeking, and the impact of social exclusion will be included as secondary outcome measures. Moreover, moderation (i.e., intervention satisfaction, IQ, age, baseline mindset, gender) and mediation effects will be investigated. Self-reported and mentor assessments will be administrated at baseline, post-test and at three (except mentor assessment) and six months follow-up. DISCUSSION: This paper describes the design of a RCT examining the effectiveness of the online mindset intervention "The Growth Factory" aimed to empower adolescents with intellectual disabilities. If effective, "The Growth Factory" makes an important contribution to the treatment and psychosocial development of adolescents with intellectual disabilities in residential care and special education. Due to the online approach, implementation will be efficient and cost-effective and therefore the intervention "The Growth Factory" can be used on large scale.
